Asked by Kirstin

Is each equation a direct Variation? If it is, find the constant of variation:

y=3/5x

-3x+2y=0

-5x+2y=9

8x+4y=12

I will do one, and you do the rest. I will be happy to critique them.

-5x+2y=9
add 5x to both sides.
2y=5x+9
divide both sides by 2
y=2.5 x + 4.5
Yes, direct variation, constant of variation is 2.5
